LIQUID-COOLER.

SPECIFICATION forming part of Letters Patent No. 307,206, dated October28, 1884.

Application filed January 31, 1884. (No model.)

"0 @ZZ -whom it may concern: Y

Be it known that I, LEWIS F. LONGMORE, a citizen of theUnited States,residing at Lowell, in the county of Middlesex and Commonwealth ofMassachusetts, have invented certain new and useful Improvements inLiquid- Coolers, of which the following is a specification.

My invention relatcsto means whereby the 1o efficiency and convenienceof such coolers are increased.

In the accompanying drawings, Figure l is afront elevation of thecooler. Fig. 2 is ahorizontal cross-section of the same on the line a: x

in Fig. 8. Fig. 3 is a vertical central crosssection at right angles tothe door of the icechamber; Figs. 4 and 5, elevations of the dischargepipe connected to a T,which is provided with a three-way cock, thevalve-case 2o being in section.

A is an outer chamber, preferably of nearly cylindrical form, to containand be lled with water, beer, or other iluid, which may be introducedunder pressure to the same through the pipe or passage C, and dischargedthrough the pipe or passage B, after being cooled in said chamber, ashereinafter described.

D is a chamber, preferably as nearly cylindrical as the door-place willallow of, and

3o placed about concentrically within the chamber A. The chamber D isprovided with a passage, E, which leads out through the outer chamber,A, and projects slightly from the same. A door, F, is hinged at H to thedoor- 3 5 place or outer end of the passage E, and shuts against theange E thereof, the iiange being beveled at E, and the door beingprovided with a corresponding bevel,` F', which shuts into and againstthe bevel E. The door also 4o has a flange, F2,.which shuts over thefront of the door-place, and which may be packed with felt or othernon-conductor of heat; or a sheet of felt may cover the entire innersurface of the door, to preserve as long as possible the ice,which, intheform of blocks or poundedup into pieces, is placed within the chamberD, the door F being securely closed by means of a handle nut or cam, H',which turns on a stud, H2, projecting from the door-frame. The

door is provided with aknob, F3. The chamber D is provided in its lowerend with a recess, G, placed directly over the inlet-pipe C, theinlet-pipe and the recess being preferably in the center of theirrespective chambers. From the recess G there are two or more ra` -`dialpassages, P, which lead out through the annular lower part of thechamber D into the space between the two chambers, in order that wateror other liquids of the ordinary temperature, and warmer than thecontents of the chamber' A, may not, when admitted through the pipe C,rise directly to the top of said ient receptacle, and does not come incontact` with the water, which is considered an advantage, as the icecommonly sold is apt to contain sawdust, sticks, and settlings. As aboveintimated, the liquid is forced into the space between the chambers atthe bottom and drawn from the top, and the pipe C may be connected witha receptacle of beer or similar beverages, or, if used to cool water,may be connected directly to the city water or other supply pipe by anysuitable well-knownjoints or couplings. If desired, anotherwater-passage, K, may be formed in the outer chamber, through whichwater may be drawn for other purposes than drinking, this passage beingof so small capacity, as compared with the water-chamber, as not greatlyto raise the temperature of the water within the latter, and beingconnected with the same source of supply as the pipe C. It' both of thepipes B K are used, they may be united above the cooler to a T, whichcontains a three-way cock, V, by turning which into different p0-sitions the water may be drawn from the cooler, (see Fig. 3,) or fromthe pipe K, (see Fig. 4,) or entirely shut off, as shown in Fig. 5, sothat in very cold weather, when ice is not required to cool the Water,orwhen for any reason it becomes desirable, the water may be takenWholly from the water-main or other source Without passing it throughthe cooler. The Water in all cases is drawn through a faucet connectedto the stein of the T.

The entire cooler is intended to be cast in a single piece, from iron,when the cooler is intended to be used for water merely; but the coolermay be formed in several parts, when it is desirable to tin the insidethereof, to prevent the inner surface from being acted on by the liquidscontained therein.

I claim as my inventionl. The combination of the external liquidchamberand the internal icecha1nber, provided witli an opening at the sidethereosaid li quid-ehamber extending above said ice-chamber and arrangedto allow theliquid to be cooled to circulate over the top of saidice-chamber, as and for the purpose specied.

2. The combination of the liquid-chamber, surrounding the icc-chamberand provided with an outlet-pipe, tlie ice-chamber provided with arecess in the bottom of the same, and the inlet-pipe arranged below saidrecess, as and for the purpose specied.

3. The combination of the liquid-chamber, surrounding the ice-chamberand provided with an outlet-pipe, the ice-cliamber provided with arecess in the bottom of the saine,

and passages leading from said recess outward throughA the lower part ofsaid ice chamber,

and an inlet pipe arranged below said recess,
